Hi all, a bit out of my depth on some github actions / ubuntu / libxml2 stuff and looking for some help!
I have a workflow that is failing on Ubuntu 16.04 with R 3.5.3 due to
xml2 not being able to compile (starting at https://github.com/Sage-Bionetworks/magora/runs/1981407928?check_suite_focus=true#step:9:2669 and ending at https://github.com/Sage-Bionetworks/magora/runs/1981407928?check_suite_focus=true#step:9:3256), but it works just fine on Ubuntu 16.04 with R devel: https://github.com/Sage-Bionetworks/magora/runs/1981407894?check_suite_focus=true#step:9:2933
The last passing build for this was in December: https://github.com/Sage-Bionetworks/magora/runs/1488099857?check_suite_focus=true#step:9:2557, but I haven't changed anything in the workflow, or even the version of xml2 (1.3.2) required since then (tracked in the lock file via renv).
From poking around on similar errors, seems like this might be related to C++11 (https://github.com/r-lib/xml2/issues/294 and https://github.com/r-lib/xml2/issues/231) but really out of my depth when we start talking about that, especially how to provide a version of the compiler in github actions.
Appreciate any pointers or guidance!
